Application filed January s, 191?. .Seria1No. 141,088.

ing a part of a wrench designed for use in connection with automobile wheels having radial and lateral bolts for tens'ioning and fastening the tire carrying rim upon said wheel.

It will be understood, however, that this improved universal joint can be used wher ever a universai-connection. desired and the principal object of this invention-is to provide a universal joint whichis exceedingly simple in construction, consists of a minimum number ct parts, is cheap to manucorresponds in size with the driven member fecture and easy to manipulate.

The wrench embodying my improved universal joint is designed for use upon Wheels having redial bolts for tensioning therim upon the Wheel body, such as shown in my Patent No. 1,188,200 June 20, 1916, and is intended to supersede the ratchet Wrench-being quicker, easier, more positive and surer in. operation.

Broadly speaking, my invention consists of a. driving member and a driven member, said members having engaging means adapted to hold said members in universal moving relation to each other, and my improved wrenclrrnay be said'to comprise a handle having at driving member at the end thereof, which driving member is connected in universal moving relntionwith a socket member Which'is adapted to receivelthe bolt or not to be turned.

The inventinn also includes/remaindetail features of construction and also certain novel features ofconibinetion, all of Which will become apparent as the descriptionprm ceeds.

In the drawings forming a part of this specification, Figure 1' is a, view showing the p 'sctiesl application of my invention; Fig. 2 is h detail view partly in section and illustrating the manner of using the same; Fi 3 detail sectional view of the driving and driven member; Fig. sis a View of the pa detached or disconnected.

In carrying out. my invention, I employ a driven member. A which is made of metal and comprises a central portion having a polygonal shaped aperture, or socket A which receives the head of the bolt or the nut to be turned. The member A is preferably formed with integral retaining fingers A spaced at suitable distances apart and having their ends slightly enlarged or eX- panded laterally as shown at A T he tingers A'-'- together with the central portion are curved upon the are of a circle so that the driven member as a Whole is essentially hemispherical in shape; and the outer ends of the fingers are rounded off or cut away as shown at'ik j The curved form of the body a-nd fingers and these cut off edges enables'one to use this type of wrench upon bolts and nuts arranged upon the side of a Wheel folly upon which an overhanging flanged rim is itrranged.

and is formed with lateral projections B, which fit between the spaced retaining fingers A and theends A [of the fingers pre-- vent these parts becoming disconnected, but the retaining fingers and the lateral projections are so constructed and so designed that the members A and B havea free universal movement with reference to each other. A

The driving member B is comiected to the end of a handle C and turns therewith, the handle beingpreferably made from a qpiereo rod iron of suitable dimensions bent back upon itself at its outer end to rovide :1 convenient and suitable sized handle Q, the opposite end being reduced shown at (Fund fitted into and secured in The driving member is zilsoof metal and the central opening B produced in the driv parts instead of beingg integral parts .thereof, and'they can be of any shape which Will maintain these parts in close universal Working relation with each other,

In operation the socket portion or mernber is fitted upon the bolt to be turned, and then the handle is rotated, ca ng driven.

With it the driving member, which in turn rotates the driven member which is in engagement with the bolt or nut to be turned. The handle is of sutficient length to have the handle C clear the hub, when placed at an, oblique angle as shown in Fig. 2, but owing to. the universal joint between the --parts A and B the bolt will be quickly turned in the desired direction. The wrench is equally as well adapted for turning the bolts or nuts of lateral clampsupon the felly of the wheel, and can be used wherever a socket wrench of the usual construction can be employed. The parts being punched or forged, the Wrench can be quickly and easily made and at a comparatively small cost.

While I have shown and described the in terengaging parts of this wrench shaped and-connected for universal movement, it is obvious that they can be rigidly connected her, the engagement between the socket and driving members being capable of a uniemons lateral projections, a socket member having radial projections, said projections being adapted to engage each other and constitute a universal joint, one of said members being provided with means to prevent disconnection.

4. A wrench comprising a socket'mcmber having curved radial fingers provided with enlarged free ends, a driving member having lateral projections adapted to fit between the fingers of said socket member, and a handle connected to said driving member. 7

5. A wrench comprising a handle termis nating in a driving member having laterally projecting portions, :1 socket member having an apertured central portion and upturned side portions together with means to prevent disconnection of said parts.

In testimony whereof, I hereunto atiix my signature,
